5 RESTful APIs REpresentaNonal State Transfer (REST): Client- Server Stateless PlaNorm & language- independent Standards- based (runs on top of HTTP) Can easily be used in presence of firewalls NITRO (RESTful service on NetScaler): Communicate with NetScaler programma*cally Human readable HTTP- based interac*on NITRO SDKs available for mul*ple languages (Java, Python,.NET, REST) 5

6 RESTful APIs A way to interact with an API via series on HTTP calls VERB: HTTP Method (GET, PUT, POST, DELETE, OPTIONS) URI: the URI of the resource on which the opera*on is performed HTTP Version: usually "HTTP v1.1" Request Header: contains metadata (forma@ng, etc.) Request Body: actual message content 6

7 NITRO A way to interact with an API via series on HTTP calls HTTP Method (GET, PUT, POST, DELETE, OPTIONS) There are two basic URL stems to use with Nitro: h[p://<nsip>/nitro/v1/stat/ h[p://<nsip>/nitro/v1/config/ > en*ty and system sta*s*cs > configura*on opera*ons Add the resource type (and in some cases also the resource name) to the URL: h[p://<nsip>/nitro/v1/config/nsfeature/feature Specify an acnon (bind, add, enable,...) for the URL: h[p://<nsip>/nitro/v1/config/nsfeature?acnon=enable 7

8 NITRO A way to interact with an API via series on HTTP calls Specify the Content- Type in the Request Header: Content- Type:applica*on/vnd.com.citrix.netscaler.nsfeature+json Add the JSON payload to the Request Body: 8

9 NITRO A way to interact with an API via series on HTTP calls 9

10 NITRO Why use NITRO? Simple HTTP calls for data exchange between systems Programs or scripts can include NetScaler sta*s*cs If server load = max, then automa*cally enable more services on the NetScaler Build your own automated NetScaler deployments Essen*al for datacenter automa*on/sdn NITRO Enhancements in 10.5 Python SDK File Opera*ons (automa*cally upload license and cer*ficate files) New APIs (techsupport, batch, nstrace) SSH Commands (ping, traceroute) 10

11 NITRO requirements NetScaler 9.2 or later Authen*cate with an account with execute permissions Access to the NetScaler NSIP (or SNIP) with Management Access enabled REST Client or programming language Use a client like curl & POSTMAN, or Download and install the NITRO SDK for your programming language 11
